What current does burn the motor -> peak or continuous?

[Just]

Hi All,

What current does burn the motor -> peak or continuous?

Which current is more dangerous?

Are motors usually rated for the peak or continuous currents?

I have a 48V motor, which was rated by a manufacturer as a 350W one, but its controller is set to 17Amps for continuous current (48V*17A=816W) and to 22Amps for a peak current (48V*22A=1KW). How so?

Thank you!

Th only way to test when the motor will burn is testing by yourself hahaha

Peak is for short period and continuous....>>>it can handle the amps for long period.

So, what current is more dangerous? How much is possible to over-current the motor?

How much the motor can consume the current? Infinitely? Do the motors usually have some over-current ? circuit or this is the controller's responsibility?

I don't know how much current is dangerous for a motor, it depends of the design of the motor.
So you should ask the maker.

Motor with thick windings/copper wires can comsumes more amps.
Normally motor don't have any current protection.

Well some of them have a temperature sensor for protection >>>>to much current >>>>more heat.

So the contoller is the brain for safe operation.

In geared motors  Nylon cogs can get mashed up with too much torque/amps pushing them. 
Too much power through thin wires will cause heat/resistance and can make wires melt in the motor.
You can control amps with programable controllers and with cycle analysts. It all depends on what your battery can deliver.

Waauww that's a nice feature controlling the amp.
I can d this while ridding?

Does it work with Kelly controller?
I don't a CA3, I have just a simple Turnigy wattmeter

[Just]

Yes, Kelly Controllers may work in two modes - Boost and Economic. As for the Economic mode, it's about 60% in the current limit of the Boost one. These modes are switchable during the ride.

If you install a simple 10K NTC in the motor you can even have the CA3 limit the amps based on the temperature in the motor. This makes overwatting a bit safer.

With the latest firmware you can change power settings while riding.

Aaha I didn't look at those features... While using the controller....
So I don't have buy the expensive CA3, just a simple switch

Thanks!

What is the 10K NTC and what is CA3?

With the latest firmware you can change power settings while riding.

What Controller do you talking about?

[Just]

How to use/install the 10K NTC thermistor into the motor? Do you have some instructions / guides how to do so?

[MAGICPIE3FOCUSPOWER]

Well it's quite simple, just install nearby the copper windings.

[Just]

I'll try, thank you! Should the thermistors be connected to the Controller's pins directly without any additional components between them?

[MAGICPIE3FOCUSPOWER]

Yup just to the temperature sensor input pins.

[Just]

Great! Thank you! I'll try! Would you recommend any specific NTC?
